STOPPEB.

Application fi1ed August 28, 1915.

To all whom it may concern Be it known that I, J osnrrr Marmnaua, acitizen of the United States, and a resident of the borough of theBronx, county of the Bronx, city and State of New York, have inventedcertain new and useful Improvements in Stoppers, of which the followingis a specification.

This invention relates to stoppers, and has for its object to provide animproved stopper which will supplant to a large extent the stoppers madeof rubber or cork, as now generally used.

For this purpose the invention consists of an improved stopperconsisting of cotton saturated with gelatin and kaolin, and alsosaturated with paraffin, and the invention consists further of theimproved Drocess of making such stoppers.

In the accompanying drawings, Figure 1 shows a sectional side view of amold in which the stoppers are formed, and showing the cotton being fedto a rapidly rotating spindle; Fig. 2 shows a similar view with thecotton fed around the spindle or pins until the mold is filled; Fig. 3shows a similar view with the cotton filling the mold, but with thespindle withdrawn, and shows the stopper itself ready to be withdrawnfrom the mold; Fig. 4: shows a side view of a completed stopper; Fig. 5shows a plan view thereof; Fig. 6 shows a side view of a smaller sizedstopper; Fig. 7 shows a plan view thereof; and Fig. 8 shows a stopperwound around a wire formed into a loop so as to permit the ready removalof stoppers from bottles and the like.

Similar reference numerals indicate corresponding parts throughout thevarious views.

Referring to the drawings, and more particularly to Fig. 1, the mold 10is provided with an opening 11 through which a pin or spindle 12 passes.The spindle 12 is rapidly rotated about two thousand revolutions perminute, and during its rapid rotation, the cotton is fed in thedirection of the arrow 13 toward the spindle. This cotton is saturatedwith gelatin and kaolin, and

brings the cotton into a yieldable mass which, on the rotation of thespindle, causes the cotton to be moved with the spindle and subjected tocentrifugal forces, and by that and the rapid rotation, the cotton isformed into various layers tightly contacting with each other.

Specification of Letters Patent.

Serial No. 47,762.

in Fig. 2 is shown the cotton around the spindle so as to fill the mold,which mold has a configuration similar to the form which it is desiredthat the completed stopper should have, and, similarly, in Fig. 3,

this mold is filled and has the spindle withdrawn, whereby the cottonnow formed into a stopper, shaped by the mold, is in a positlon wherebyit may be readily taken out. After the thus-prepared stopper is takenout of the mold, it is placed into a baking oven at moderate heat, whichcauses the gelatin and kaolin to dry and the various layers of moleculesof the cotton to be tightly compacted. After the stoppers are thusdried, and while still warm, they are inserted into a hot parafiin bathheated to 1&0", in which is mixed white rosin, and the paraffin entersinto the interstices of the cotton and fills them up, thereby making theprepared cotton stopper impervious to moisture and liquids. Of course,the molds or forms can be shaped into any shape or sizes, and stopperscan thus be produced of any sizes, as desired. If it is desired toprovide a stopper with a handle whereby it may be readily withdrawn froma bottle, a wire is arranged to have its ends parallel with each other,and the cotton is wound around and forced against this wire core by therotating and centrifugal actions, and thereby becomes an integral partof the stopper. Such parallel wires are indicated by 15 and 16 in Fig.8, and they are formed into a loop 18 which may be readily inanipulatedby the user of the stoppers.

By my improved invention, a very satis factory substitute is Providedfor the present stoppers of cork and rubber, and a very sanitary anduseful article is provided, which is absolutely air-proof andliquidtight.

As cotton in its natural form is the nearest product to the cork wood,it, when compounded as described above, answers the same purpose inevery instance, and as the various sized molds lend themselves readilyto the production of any shape or size of stopper, a useful article isproduced. As the specific weight of the finished article is about thesame as that of the cork stopper, the same advantages follow its use.Such an article when manufactured will not alone be a great benefit tothe public in general, but also to the cotton planters, and a new marketwill be created for that product.

ers of cotton saturated With gelatin and kaolin, dried and paraffined,and a stem embedded therein.

In testimony that I claim the foregoing 1-5 as my invention, I havesigned my name in presence of two subscribing Witnesses.
